CORNER, FASTENING FOR BEDSTEADS.

Application filed August 22, 1921.

To all whom it may concern: I

lie it known that 1, WILLIAM A. K0011, a citizen of the United States,residing at lllvansville, in the C(lllllty oi Vanderbnrg and State oilIndiana, have invented certain new and useful Improvements in Corner iastenings for liedsteads, of which the "fol lowing iii a full, clear,and. exact specific ty tion.

My invention relates to bedsteads and has reference iorc particularly tocorner fastenings for metal beds using the ordinary angle side railswhereby the side rails may be reversed and adapted to support either theordinary box spring bottoms, or ts.

in object oi? the invention is to provide a corner fastening thnt'shallbe simple in construction, positive in action, and which may be usedwith any "form of bed posts whether o metal or wood.

Another object of the invention is to pro- 'vide a corner "fastening forbeds which while jlorniing an eiiicient coupling for the side rails andcorner posts will also securely lock the coupling against lateral tvisting or turn ing oi? the side rails.

With the above and other objects in view my invention consists incertain novel features of construction and arrangement of parts as willbe hereinafter fully described and pointed out in the claim. referencebeing had to the accompanying drawing. forming a part hereof, in which:

Figure 1 is a perspective view showing my improved corner fastening asin use in one arrangement of parts,

Figure 2 is a similar view showing reverse arrangement of the parts,

the

Figure 3 is a transverse section taken as on line 3-3 of Figure 1,

Figure at is a vertical section of: the arrangement as shown in Fig. 1,

Figure is a perspective view oi the headed member of the "fasteningwhich is carried by a side rail,

Figure 6 is a perspective view of a. socket member which is carried bythe corner posts of the bed.

Referring more specifically to the draw-- ing it will be noted that thereference numeral 1O denotes the corner post of ametal bed, the postbeing indicated as of rounding formation by dotted lines it the mostconvenient location on the post, which may of course be polygonal orhave {la t faces, the member 1.1 of the tasted Serial No. 494,342.

wings provided with openings 15 by which the wings and hence the bracketmay be bolted or riveted to the corner post.

Through the front face of the bracket an opening 16 is made, the generalshape of this opening being polygonal.

A narrow slot 1'? is cut through the rent face of the bracket andextends dowz'm ardl' a sui able distance below the opening 16 with whichit merges. B cutting this slot through the race of the bracket spacedapart .tlanges or ribs 18' are formed and the rear face of these flangesor .ribs is sing-11th rounded or tapered to form wedge or cam faces. H

The front "face of this member 11 is flat and smooth and is bordered ateach side by the vertical flanges 19-l.9 extending from the upper to thelower end of the face, the inner or opposing faces of these flangesbeing slightly tapered or converging from the outer edges to the face asindicated by the reference character 20, as will be plainly seen l:reference to Figure 3 in the drawing. This disposition of the sideflanges results in forming virtually a wide groove in the bearing faceof the bracket member.

The other member of the fastening, the fastening as a unit consisting oftwo members, is to be secured to the side rail 21 or cast integral withit, and consists of a stud 22 projecting 23 of the member, the studbeing provided with a head 2% which extends laterally at each side ofthe stem of the stud.

This stud is preferably cast integral with the vertical web 25 whichconnects the upper and lower portion of the member, said web 25 beingcast integral with said upper and lower portions and extending upwardlysome distance on the back face oi the member to brace and strengthensame, as shown at 26.

Thestudded member is also provided with the vertical web 27 and thehorizontal web 28 respectively which are riveted to the correspondingflanges of the angle side rail. At the edge opposite the vertical web 27the member is provided with an inte ral vertical flange 29 which is castintegral with the body portion and the horizontal web,

from a vertical bearing face 28, serving to balance the parts and bravethe member at that side.

The sides of the studded member are beveled as shown at 30, orcon\"e1:*ge, the bevel being complen'lentary and correspomling to thatof the flangesv 19 on the socket member.

The trai'isversely narrow stem of the stud has as before stated the lai. 'ehead 24 the inner faces of which at opposite sides of the stem hasthe central bearing surface 2a and tapered oppositely or curved endportions 248. Thus the head will have its greatest diameter in the planeot the bearing surfaces and taper equally in both directions therefromso that no matter which end of the head enters the OIX'lllDQ l6 andnarrow slot 17 ot the other or socket member the central bearingsurfaces will come in con tact with the rear cammed or wedge :iaces ofthe ribs 18 and cause the two members to be drawn tightly together whenthe studded member is forced downwardly.

By this arrangen'ient and disposition of the bearing surfaces of the twomembers, the reversal of the angled side rails is provided for so thateither the ordinary box sp ing bottom may be used or slats, as desired.

It should be particularly noted that side flanges 19 of the socketinembendefine a wide groove-in the face of the member and as the widthof the bearing face of the stud as the width of the bearing face of thestudded member is such that it readily slides within said groove thatrocking wabbling or turning of the side rails will be prevented when themembers are coupled together.

Furthermore as't-he groove formed by the flanges 19 is a divergentgroove and the mating end of the studded member is complementa-llyconvergent, it will be seen that a very tight joint is secured, and theresistance to angular movement of the side rails is correspondinglyincreased.

claim:

A corner fastening for metal bmilsteads comprising a pair of castings,one oil. said castings including a flat bearing face having a keyholeslot therethrough and outwardly taperingflanges at its opposite sideedges, the other casting having upper and lower flat. bearing faceportions, said. portions connected centrally by an integral webextending rearwardly and upwardly, back of the upper bearing portionserfing to brace said portion, a stud or shank projecting forwardly fromsaid web, a cammed head on said stud, said stud and head adapted to fitwithin the keyhole slot of the first named casting, the side edges ofthe stud carrying casting rerersely tapered to fit within the flanges ofthe first casting, and be d awn tightly thereto by cam action of thestud head.
